Its everything a full computer or laptop is, minus the keyboard. It has a 17.8-centimeters touch-sensitive screen that responds to a stylus or the tap of a finger.
Two models from different manufac-turers are expected to hit stores shelves by spring, and Microsoft says they will be about 2.5 centimeters thick and weigh less than 1.1 kilograms about the size of a large paperback book.
It will run on a full version of Windows XP, the same operating system used on larger tablet PCs, and newly developed software called Windows Touch Pack will handle touch-screen functions.
Future editions will support Windows Vista, a version of Microsofts flagship operating system thats due out in the second half of this year.
"It really opens up new possibilities for PC use," Bill Mitchell, corporate vice president of Microsofts Mobile Platforms Division, said.
The device was unveiled at CeBIT, the annual technology trade show in Hanover, during a speech by Intel Corp. executive Christian Morales. Intel makes the Celeron M and Pentium M microprocessors that run the device.
Morales said Intel hopes to develop more chips for the device that will run faster and cooler.
So far, three companies have built working models Samsung, Asus and Chinese manufacturer Founder.
The device wont be called Origami. Instead, the company is marketing it as a category its calling the ultramobile PC, said Mika Krammer, a marketing director for Microsofts Windows mobile unit.
Though Microsoft is not manufacturing the hardware, it took a guiding role from the start.
"Weve done more than just provide the software. Weve built the reference designs to sort of get the category started," he said. "We had the first prototypes about nine months ago and started working with partners early on."
The Samsung and Asus devices are expected to be in stores by April, and the Founder device in June, Krammer said.
"A lot of the early engagement we have had has been with non-traditional PC vendors, although there is a lot of interest from traditional PC vendors as well," Mitchell said.
"It ideally brings the best of what a Windows PC is and marries it to what the best of a very capable consumer electronic device is," Mitchell added.
That, said David Bradshaw, a principle analyst with London-based Ovum, is key.
"I really would hope that it would be something that works," he said, adding that he had not seen one of the models.
"Something that is wirelessly connected. Hopefully it will have a wide range of wireless options so that you would be able to use Wi-Fi when available or a (wirelesss) carriers network if you can afford to pay through the nose," Bradshaw added.
Krammer said the device is expected to retail for between $600 and $1,000.
Origami, Mitchell said, will be sporting Bluetooth and Wi-Fi wireless access. At CeBIT, he said they were using their models by connecting their cellphones to it via Bluetooth.
The screen is wide, bright and easy to see, even in low light. Mitchell showed a music video on one model and a film on the other. It doesnt have its own keyboard, but since the units are designed with USB 2 ports, one could be plugged in as needed.
Other units shown had SecureDigital Card and CompactFlash memory card slots, along with jacks for connecting digital cameras, headphones and speakers.
For users who dont want to jot down notes with the stylus, the Origami has a built-in program called Dial Keys that splits a standard QWERTY keyboard into pie shapes on the lower corners of the screen so that input can be typed or thumbed in.
The battery power averages about 2.5 to three hours, and it will have up to a 60-gigabyte hard drive.
Mitchell said the device is aimed at consumers who want to have the full power of a PC while on the go but dont want to lug around a heavy laptop or desktop PC.
"We think that for most people, this is more of a replacement for the classic consumer electronic devices that theyre buying with disposable income," he said.
While its not compact like an iPod, it does play music, store and display photos like a digital picture frame, and show films and TV shows. For someone sitting on a plane, some models have a stand-in back to prop up the device for easier viewing.
Bradshaw said if the screens size appeals to consumers, it could be an impetus for wireless carriers to offer more video-on-demand.
"It may be the dream device for all these mobile operators that actually want people to watch video over their networks," he said.
Michael Gartenberg, an analyst in Jupiter Researchs New York office, said he thinks the device has potential.
"The whole Origami concept may very well change what devices people are going to carry with them," Gartenberg said. "Its not a pocketable device, but its certainly small enough to be kept close at hand, and the fact that it runs Windows means that it can do a variety of tasks, from productivity to games to media consumption."
